ABSTRACT
As we enter the second decade of the 21st century, while looking back at the first decade, we are reminded of the introductory sentences of A Tale of Two Cities by Charles Dickens (1859/1997, p. 13):
It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair.
